TL;DR: Yes, Bulgaria really has a 10% flat income tax – the lowest headline rate in the EU. But “10%” is income tax only. Freelancers in a liberal profession get a 25% expense deduction that cuts the effective income tax to about 7.5% of gross – and then mandatory social security and health contributions of 27.8% (or 31.3% with sickness cover) come on top, charged on a capped monthly base (as of August 2026: minimum ~€172/month, maximum ~€639/month). For a professional-level freelance income the realistic all-in rate is around 25%, not 10%. A single-owner company (EOOD) pays roughly 14.5% on distributed profit – but an owner who actually runs it still can’t escape the social-security layer. Bulgaria is genuinely low-tax, especially for high earners, but nobody on a normal income pays “just 10%”.

You have seen the posts. “Move to Bulgaria, pay 10% tax.” It gets shared in every nomad group, screenshotted onto every “best countries for freelancers” list, and repeated until it sounds like settled fact. And the 10% is real. What’s missing is everything that sits on top of it – which is why the same question comes up on Reddit again and again: if the tax is 10%, why is my accountant quoting me a quarter of my income?

Here is the honest arithmetic, checked against the Bulgarian tax and social-security authorities rather than a listicle – so you can decide whether Bulgaria actually works for your numbers.

Yes, Bulgaria’s 10% flat tax is real

Bulgaria charges a flat 10% personal income tax on employment income, income from civil and freelance contracts, rent and most other personal income. There is no progressive ladder – the person on €15,000 and the person on €150,000 pay the same headline rate. It is genuinely one of the simplest and lowest income-tax regimes in the European Union.

One exception trips people up: a registered sole trader (the Bulgarian ЕТ business form) is taxed at 15% on business profit, not 10%. The 10% flat rate is for individuals and freelancers, not that particular structure. Keep the two apart.

The 25% freelancer deduction – and where “7.5%” comes from

If you work in a statutory liberal profession – consultant, accountant, translator, architect, engineer, IT professional, journalist, artist, and so on – or you earn under a civil (non-employment) contract and aren’t registered as a merchant, Bulgarian law gives you an automatic 25% “recognised expenses” deduction. You don’t have to prove those expenses; the deduction is built in.

The maths is simple. On €100 of gross revenue, deduct €25, leaving €75 taxable. Ten per cent of €75 is €7.50 – an effective income-tax rate of 7.5% of gross. (Lawyers and certain author/royalty income get an even higher 40% deduction.) That €7.50 figure is where the “practically nothing” reputation comes from.

But read that carefully: 7.5% is income tax only. It does not include the contributions that come next – and those are the whole story.

Bulgaria’s social security and health contributions: the part the 10% headline leaves out

This is the piece the viral posts skip, and it’s the reason the real number is so different from the advertised one.

If you’re self-employed in Bulgaria, you pay social security and health contributions that are entirely separate from your income tax. As a self-insured person the mandatory rate is 27.8% – that’s 19.8% towards pension plus 8% health – or 31.3% if you opt in to sickness and maternity cover. (Self-employed people don’t pay the unemployment or work-accident funds, which is why this is lower than the ~32-33% combined figure you’ll see quoted for employees. Don’t confuse the two.)

Crucially, those percentages aren’t charged on your whole income. They’re charged on a declared monthly “insurable income” that sits between a floor and a ceiling. As of 1 August 2026, that floor is €620.20/month and the ceiling is €2,300/month. So the mandatory contribution runs from about €172/month at the floor to about €639/month at the ceiling – and above the ceiling, you pay no more, no matter how much you earn.

That cap is what makes Bulgaria’s system genuinely favourable for high earners – and misleading for everyone else. Because contributions stop rising past €2,300/month of insurable income, they shrink as a share of a large income and swell as a share of a small one. There is no income level at which a genuine full-time freelancer pays “just 10%”, or “just 7.5%”, all in. The contributions are the missing 20-odd points.

(A stale-figure warning for anyone cross-checking: any guide quoting a maximum base of ~€1,917 or a minimum around €477 is using 2023-24 numbers. The thresholds rose in 2026. Wage-linked figures like these go up over time, not down.)

So what tax will you actually pay in Bulgaria?

Put the layers together and the picture is very different from the headline. These are illustrative, simplified figures for a liberal-profession freelancer (25% deduction, contributions on income after that deduction, contributions deducted before the 10% tax) – confirm your own case with an accountant:

  • ~€18,000 gross: after the 25% deduction you’re inside the contribution band, so you pay 27.8% on roughly €1,125/month plus 10% on what’s left – an all-in rate of about 26%.
  • ~€40,000 gross: now above the contribution ceiling, so contributions cap out around €639/month; add the 10% tax on the remainder – about 25% all-in.
  • ~€100,000 gross: contributions are still capped at that same ~€7,700/year, so they fade to a small share; income tax dominates – and the all-in rate drops to roughly 14-15%.

Read that shape carefully, because it’s the real headline: Bulgaria rewards high earners and taxes modest ones at rates that look nothing like “10%”. For most working freelancers the honest number is in the mid-twenties per cent – low by Western European standards, but not the fantasy.

Freelancer or company (EOOD): which is cheaper in Bulgaria?

The other endless Reddit debate is whether to register as an individual freelancer or open a single-owner limited company – an EOOD. The company route looks seductive on paper: 10% corporate tax on profit, then 5% tax on dividends when you take the money out. Distribute all the profit and the combined burden is about 14.5% – lower than a mid-income freelancer’s all-in rate.

Here’s the catch that sinks the “open an EOOD and pay no social security” advice: an owner who actually works in and manages the company must insure themselves – normally as a self-insured person, on exactly the same 27.8%/31.3% regime and the same capped base as above. Owning shares passively triggers nothing; running the business does. You don’t escape the contributions layer by incorporating – you just move it.

Add the running costs – an EOOD needs proper accounting (roughly €60-150/month depending on VAT and volume), annual filings, and more admin than a freelancer – and the company only really pays off above a certain income, where the dividend structure beats paying contributions across a wider band. Below that, the simplicity of freelancing usually wins. It’s an income-level decision, not a universal answer, and it’s worth modelling with an accountant rather than a forum thread.

Bulgarian VAT: the registration threshold most people get wrong

You must register for Bulgarian VAT once your turnover exceeds €51,130 in a calendar year (the exact euro conversion of the old 100,000 lev threshold – it wasn’t cut, just re-denominated when Bulgaria adopted the euro on 1 January 2026).

Two things catch remote workers out:

  • EU business clients: services to VAT-registered businesses elsewhere in the EU are reverse-charged (you don’t add Bulgarian VAT), but supplying them usually requires a special registration before your first invoice, regardless of the €51,130 threshold, plus EU sales reporting.
  • Non-EU business clients: generally outside the scope of Bulgarian VAT, so you invoice without it.

If most of your clients are abroad, get this mapped by an accountant early – the registration triggers are easy to miss.

Does Bulgaria’s digital nomad visa change your tax?

No – and this is the point most visa blogs get wrong. Bulgaria’s digital nomad route is a residence permit, not a tax status. Holding it does not grant a tax exemption and does not by itself make you tax resident or liable for Bulgarian social security.

What decides your tax is the ordinary residency test (below). What decides your social security is which country’s system you fall under – governed by EU coordination rules, an A1 certificate, or a bilateral agreement – and whether you register a Bulgarian self-employed activity. A nomad keeping genuinely offshore work and not registering a local liberal profession isn’t automatically a Bulgarian self-insured person just because they hold the permit – but that “applicable law” question has to be established properly, not assumed.

When do you become tax resident in Bulgaria?

You become tax resident if any of these is true: you spend more than 183 days in Bulgaria in any 12-month period; your centre of vital interests (family, home, where your business is really run) is in Bulgaria; or – weakly, on its own – you have a permanent address there. Once resident, Bulgaria taxes your worldwide income. Before that, only Bulgarian-source income, subject to any treaty – and Bulgaria has over 70 double-tax treaties in force, so genuine double taxation is usually avoidable.

The practical warning: tax residence and visa residence are different things. You can hold the nomad permit and not be tax resident if your stay is short – but settle in for a year, and residence, worldwide income and (potentially) local contributions all come into view.

The honest takeaway

Bulgaria is a genuinely low-tax country – and for a high-earning freelancer or a well-structured company, it can be one of the most efficient bases in the EU. But the “10% country” story is marketing, not maths. The 10% is income tax alone; the real cost for a normal working freelancer, once social security and health contributions are counted, sits in the mid-twenties per cent. That’s still competitive – it just isn’t the number on the poster.

Before you move on the strength of a screenshot, model your income under both the freelancer and company routes with a Bulgarian accountant. The savings can be real. They’re just never as simple as one number.

Frequently asked questions

Does Bulgaria really have a 10% flat tax? Yes – a flat 10% personal income tax on most personal income, the lowest headline rate in the EU. But it’s income tax only; mandatory social security and health contributions are charged separately on top.

What’s the real all-in tax rate for a freelancer in Bulgaria? For a professional-level income, realistically around 25% once the 27.8% social and health contributions (charged on a capped monthly base) are added to the ~7.5% effective income tax. High earners pay proportionally less because contributions are capped; modest earners pay a higher effective rate.

How much is social security for the self-employed in Bulgaria? 27.8% mandatory (or 31.3% with sickness/maternity cover), charged on a declared monthly insurable income between about €620 and €2,300 as of August 2026 – so roughly €172 to €639 per month.

Is an EOOD company cheaper than freelancing? It can be at higher incomes (about 14.5% on distributed profit), but an owner who actively runs the company still has to self-insure, and the company carries accounting and admin costs. Below a certain income, freelancing is usually simpler and no more expensive.

Does the Bulgarian digital nomad visa mean I pay 10% tax? No. The visa is a residence permit, not a tax status. Your tax depends on whether you become tax resident (the 183-day / centre-of-vital-interests test), and your social security on which country’s system applies to you.

This is general information, not tax or legal advice. Rates, thresholds and rules change and depend on your exact circumstances – verify with the Bulgarian National Revenue Agency (NRA) or a qualified Bulgarian accountant before acting.
